displayed message. In this instance–no further operation of the instrument is
possible until the fault has been corrected.
When the POWER switch is placed in the OFF position the terminals remain
in the condition prevailing. Xitron Technologies recommends selecting the
“Standby” state prior to switching the POWER
switch OFF, to afford the
highest level of protection both to any circuitry connected to the instrument
and to protect the instrument from inadvertent application of external signals.
Connecting to the OUTPUT Terminals
To deliver voltage, current, or temperature to your test equipment, connect it
to the binding-post terminals using banana plugs, spade leads or wire. When a
positive polarity of output is requested, the RED terminal is the positive
terminal and has the requested current flow.
Notes:
1)
The terminals are automatically configured as input terminals when the
2000M instrument is set to the “Measure” mode.
2) In cold junction compensation mode (CJC), the output connectors are
wired in parallel with a female rear-panel mounted connector.
Displaying Instrument Status
The DC calibrator instrument offers the flexibility of setting the output level
and setting the instrument’s status to “Standby” or “Operate”
. This is done
following the application of power. The display shows the output level and
status following the messages associated with the power on internal tests.
With the instrument in the user-selectable “Standby” mode, the output
connectors are disconnected internally.
The following example is seen in “Operate” status, which means the output
level is actually being produced at the output terminals of the instrument.
Examples of the output level and status displays are:
< +10.00000mV >
The following example is seen in “Standby” status, which means the output
terminals are open circuited internally.
<+ 10.00000mV Stby >
